Hello friends, I hope you all are doing well. Today, I am going to share the 5th tutorial of Section-III in our Raspberry Pi Programming Course. In our previous tutorial, we have seen the interfacing of a PIR Sensor with Raspberry Pi 4. In today's tutorial, we will interface an Ultrasonic sensor with Raspberry Pi and will use Python to perform its calculations. So, let's get started:
Components:Here's the list of components, we are going to use in today's project:
Raspberry Pi 4
Ultrasonic sensor
Male-to-female jumper wires
Breadboard1k ohm resistor
2k ohm resistor
What are Ultrasonic Sensors?
An Ultrasonic Sensor consists of a transmitter and a receiver, the transmitter emits the ultrasonic wave, which after hitting some ob ...
Hello friends, I hope you all are having fun. Today, we are going to share the 7th tutorial of Section-III in our Raspberry Pi Programming Course. In the last tutorial, we interfaced a DHT11 sensor with Raspberry Pi 4. Today, we are going to interface another temperature sensor i.e. DS18B20 with Raspberry Pi 4.
DS18B20 is a popular temperature sensor especially in severe/critical environments i.e. chemical plants, mines, industrial sites etc. because of its 1-wire operational technique and accurate readings up to 4 decimal digits.
Project Description
Today, we will interface a DS18B20 temperature sensor with Raspberry Pi 4 and will display the values on a 16x2 LCD.Let's have a look at the components required for this project:

Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us how to use a raspberry pi as a DNS server. We also looked at the benefit of this DNS server. This tutorial will teach us to set up Raspberry pi as a VPN server.
This is an excellent method for increasing your network security and getting access to your local area network from the world wide web, but setting up your VPN server might be a challenge. Pi VPN uses a guided install to turn your Raspberry into a low-cost, high-performance VPN server.
What is Pi VPN?
It is an OpenVPN server optimized for all Raspberry platforms above pi 2. It allows you to access your home network over the internet safely and securely. Smart devices and your network can ...
Greeting, and welcome to the next tutorial of our raspberry programming tutorial. In the previous tutorial, we learned how to build a smart attendance system using an RFID card reader, which we used to sign in students in attendance in a class. When it comes to building a face-recognition program on a Raspberry Pi, this tutorial will show you how. Two Python programs will be used in the lesson, one of which is a Training program that analyzes a collection of photographs of a certain individual and generates a dataset. (YML File). The Recognizer application uses the YML script to detect a face and afterward utters the person's name when the face is detected.

Hello friends, I hope you all are doing great. Today, we are going to share the 2nd tutorial of Section-VIII in the Raspberry Pi Programming Course. In the previous tutorial, we interfaced a Barcode Scanner with Raspberry Pi 4. In today's tutorial, we will discuss how to set up a web server in raspberry pi. So, let's get started:
Components Required
We are going to use the following components, in today's project:
Ethernet cable
MicroSD card
Keyboard
Mouse
HDMI cable
Monitor
Expand FileSystem
When configuring a Raspberry Pi, select the expand FileSystem option to ensure that all of the Micro SD storage is allocated for the operating system and modify the default Pi passwords to protect your server from attacker ...
Greetings, and welcome to another tutorial in our series on the raspberry pi 4 Python programming. The previous guide covered the basics of transmitting data over the radio using the nrf24l01 chip in Pi 4. We also learned about interfacing Arduino and raspberry pi 4 and sending radio signals between the two devices. However, this tutorial will walk you through building a Raspberry Pi-based mobile phone with a microphone and speaker for making and receiving calls and reading text messages (SMS). This Project also serves as a proper GSM Module for the Raspberry Pi interface, with all the necessary Code to run the most fundamental features of any modern smartphone. First, we will understand what gsm is, its architecture and how it works, then we will learn how to program it in our pi 4; there ...
Hey Friends! Electronic experts always strive to develop new electronic devices that meet the needs and requirements of the customers. Technology has been evolved remarkably well where devices are becoming compact and composed. Using old conventional ways to develop electronic devices are becoming obsolete that occupied more weight and space, turned out to be expensive and capable of doing fewer number of operations. Today, I am going to discuss the details on the Introduction to Raspberry Pi 3. It is just like a small computer that comes with CPU, GPU, USB ports and i/o pins and can be connected with external peripherals and helps in running number of operations like regular computer. First generation Raspberry Pi was developed in 2012, with the ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to Install Raspbian on SD Card for Raspberry Pi 3. Today, I am going to start this new tutorial series on Raspberry Pi 3. In this series, we will first cover the basic tutorials for beginners and in the second phase, we will interface raspberry Pi 3 with different sensors and modules etc. In the third phase, we will involve cloud computing and will upload different data over to web server. I will take it step by step from basics to pro. I hope you will enjoy it. You should first have a look at Introduction to Raspberry Pi 3, where I have discussed the basic overview of this board, along with what it is capable of doing. Consider it a zero tutorial o ...
Welcome to the next tutorial of our Raspberry Pi programming tutorial. The previous tutorial showed us how to Interface weight sensor HX711 with pi 4. We learned that a weight sensor HX711 and load cell could be easily interfaced with a Raspberry Pi 4 with careful attention to wiring and software configuration. However, now we're one step ahead of that by using the Internet as the wireless medium to transmit the message from a Web browser to an LCD screen attached to a Raspberry Pi. This project will be added to our collection of Internet of Things (IoT) projects because messages can be sent from any Internet-connected device, such as a computer, smartphone, or tablet.
A bulletin board serves as a vital means of communicating and collecting information. Notice boards are common at many pu ...
Welcome to the next tutorial of our raspberry pi 4 programming course. A previous article covered connecting a Remote Control Radio Frequency Module (433 MHz) to a Raspberry Pi 4. To turn things on and off wirelessly, we programmed a Raspberry Pi 4 to act as a radio-frequency (RF) remote control. However, this guide will study how to wirelessly pair a Raspberry Pi 4 and an ESP32. After reading this article, you'll get a good grounding in the fundamentals of Bluetooth module operation between two ESP32 and Pi 4 communication.
When it comes to sharing data over short distances using Ultra High-Frequency Radio Waves, Bluetooth is one of the most reliable and effective short-range wireless communication solutions. Since Bluetooth Technology was initially conceived as a cable substitution tech ...
